请问一个错误：Yourscriptpossiblyreliesonasessionside-effectwhich.

请教一个异常：Your script possibly relies on a session side-effect which ...
详细信息是：
Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0


我在网上查找资料，大多答案是不要用session_register()方法就可以。

问题时我完全没有使用session_register()方法，直接使用$_SESSION[ 'XX ']=$XX 的方法，依然出现此警告，如何解决？
